To all whom it mayl concern:

Be it known that l, MILLARD F. Bronnen-- SON, a citizen of the United States, residing in the city and county of Kalamazofi., State of Michigan, have invented certa? new and useful Improvements in Couplinf i,.ofwi

' the following is4 a speciication.

. pcouplings. i v

This invention relates to im N .,evements in My improved cou .ling islparticularlyI designed andadapted y Ineas a coupling for pipes to tanks, such asthe: Siphon or ball cock pipes'for flushing tanks, and the supply pipes for such tanks, although it is adapted "for use in various other relations.

Then'iain objects of this invention are;

first,l to provide an improved coupling which may be satisfactorily produced without the necessity.; of threading machine work in the production or finishinglthereofand of such strength as to. effectively support the 'gooseneck when made integral therewith g. second, to provide -an improved coupling which is very strong and durable, although-,the same may be made of such material as -castiron and be made comparatively light;- third, to

embodying the features `of my invention;

provide an improved coupling, the parts of' which 'may be quickly assembled` or disassembled, and also ene which may be quickly attached or .detached from a tank Fig.l 2 is a detail vertical section, taken on a line corresponding to line 2-2 of Fig. 1;.

` ln the drawing, the sectional views are taken looking in the direction fof the" little arrows at the Vends offthes tion'fl'ines, and

Referring to the drawiiigfthe main-coup ling member 1 is adapte'ldolpbge' f arranged through'the bottom ofla tank, :ts/'21.1" The coupling member 1 is p'ir'mIidedwith`J afflange 3 adapted toengage tlife "inside" of 'th'efb'ottom of the tank, a gasket, as4,1beingpreferably arranged under the lian'g'e.` At its lower end, the couplingmember'fl is "frdvided'jwith pairs of oppositely-disposed'. ugs, las 4 5-5, i

adapted to engage thel fiifricljersideIof the` tank bottom, as clearly illustratedfin'fthe drawing.

This nut is provided witha pairoofspiral surfaces 9, on its lower edge daptedt'o lengage the upper pair of lugs Q5 hat,lpby turning theA clamping member` t" 4 ecoupling ,member is'clamped to the tankfbottom;

The coupling member efeiablyprovided with an inwardly-.projecting-,annular flange 11 at its lower 'end'for'the purppse of strengthening the same ,ang/further, for the purpose ofl'forming valflwide' bearing for the gasket 12,.`arranged betwe 'and the'flange 13 of the pipe 14; se ""Fi "ff The pipe 14 is detachablyi'se' ie oupling member 1 by mean's pling member i5, which is provided wat an inlwardly-projecting flange 16 adapted to receive' the langel of the pipe- 14. The pipecoupling memberl is adaptedto be slipped on the lower end yof the corres 'onding coupling member 1, and is provide with a pair of spirals 17 yadapted to engage the lower pair of 1 lugs 6, so that, by turning the coupling memarm 23 for the valve stem 25.

s without the necessity of machine worklor die workin inishing.' It is found, in practice,

f where it is 4attemped "to thread castiron attachments: of this class that great care must be taken in roperly centering the work and in securing the .proper thickness of the walls, as,if there is any im erfection in this'respect, the. coupling is like y'to be broken in applying the nuts thereto. By my presenty invention,-I overcome the necessity for threading and for the expensive machine work, thereby greatlyl reducing the cost of production.

This -is further reduced in that the parts may be assembled much more 'quickly than it .is

possible where they are.' threaded together. his is also of advantage in applying the attachment to the tanks, and the attachment may also be quickly removed should occasion i require, 1t being practically 'impossible for it -to become so rusted or so corrodedthat itv cannot be readily detached; whereas, when the coupling members are'threaded together.,

they frequently become so set and corro dedy-r unless formed of non-corrodible material-as to render it quite impossible to disconnect the same without destroying or seriously injuring the coupling. 1

The coupling member is preferably arran ed to turnin av direction opposite to-tliatI of t e clamping member k7 in tightening so" f that there yis no danger of the member-7 being i While accidentally loosened in adjustingthe kmember15.v

I preferably lform the goose-neck and valve seat integrallywith the main couplingr member,- as I have illustrated and describedf--as I am enabled by forming the parts as I have illustrated'to successfullyaccomplish this,-th'e goose-neck may formed'separately-,as is illustrated in Fig. 6

On one arm of the sior the device may be adapted by suitable modification-for use in yother relations than that of flushing'tanks.
